Removal Procedure

NOTE: Never clamp propeller shaft tubing in a vise. Clamping propeller shaft tubing in a vise could dent or deform the tube causing an imbalance or unsafe condition. Always clamp on one of the yokes and support the shaft horizontally. Avoid damaging the slip yoke sealing surface. Nicks may damage the bushing or cut the lip seal.
  1. Remove the propeller shaft. Refer to PROPELLER SHAFT REPLACEMENT - FRONT  or PROPELLER SHAFT REPLACEMENT - REAR .
  2. Support the propeller shaft in a line horizontal with the table of a press.

  3. Mark the propeller shaft in order to show which end connects to the transmission or transfer case and which end connects to the rear or front axle.
  4. Place the universal joint so that the lower ear of the yoke is supported on a 30 mm (1 1/8 in) socket.
  5. In order to shear the plastic retaining ring on the bearing cup, place the J 9522-3  on the open horizontal bearing cups and press the lower bearing cup out of the yoke ear.
  6. If the bearing cup is not completely removed, lift the cross, and insert J 9522-5  between the seal and bearing cup being removed. Continue pressing the bearing cup out of the yoke.

  8. Disassemble the cross from the yoke.

  9. Remove the remaining universal joint parts from the yoke.
  10. If you are replacing the front universal joint (rear axle only), remove the bearing cups in the slip yoke in the same manner.
  11. Inspect the retaining ring grooves for plastic.
  12. Inspect the bearing cup bores for burrs or imperfections.
  13. Clean the remains of the sheared plastic bearing retainers from the grooves in the yoke.
  14. The sheared plastic may prevent the bearing cups from being pressed into place and thus prevent the bearing retainers from being properly seated.
